I have been looking into the negative form of progressive in japanese.
Sites such as japaneseverbconjugator don't give a conjugation for both of those if they are not in the polite form, which makes me wonder if they exist at all.
In short, in a neutral tone, is it ok to say :
I am not eating : 食べていない ？
I was not eating : 食べていなかった ？
he doesn't want a horse : 彼は馬を欲しがっていない ？
he didn't want a horse : 彼は馬を欲しがっていなかった ？
I hope my question makes sense. Thanks a lot for your help !
